Has anybody delt with a Sercos ring fault that happens out of the blue? I am working with a CompactLogix L43 and three Kinetix 6000 drives. I ran my process for about 3hrs. non stop and then all of a sudden I get the Sercos fault with a code 16 #204. Two of my drives went to state 2 and the third just had the chaseing led's. I unplugged one of my fiber optic cables, plugged it back in and I am up and running again. Not real convinient to tell the customer to do. Tech support told me it could be a back plain communication problem, but no ideas to prove or fix this.
